1

Gather your membership info

Have your Costco membership card and a valid government-issued photo ID ready. If canceling by phone, locate your membership number (printed on your membership card or accessible at costco.com under 'My Account').

2

Choose your cancellation method

Costco does not allow online cancellation. You must cancel either in person at any Costco warehouse membership counter, or by phone at 1-800-774-2678 (Member Services). Phone lines are available during regular business hours.

3

Go to the Membership Counter (in-person) or call Member Services (phone)

In-person: Walk to the 'Membership' counter near the warehouse entrance — do not go to a regular checkout lane. Phone: Call 1-800-774-2678 and say 'cancel membership' when prompted by the automated system to reach a representative.

4

Verify your identity

In-person: Present your membership card and photo ID to the membership counter associate. Phone: Provide your membership number, full name, and address to verify identity. Only the primary cardholder can request cancellation.

5

Request cancellation and confirm refund

Tell the associate or phone representative: 'I'd like to cancel my membership.' They will confirm your account details and process the cancellation. You are entitled to a full refund of your annual membership fee regardless of how much time remains in your membership year.

6

Receive your refund

In-person: Refund is issued immediately, typically returned to the original payment method or as cash/check. Phone: Refund is returned to the original payment method and typically takes 5–7 business days to appear.
